Found this at the pick a part and it looks weird compared to my regular focus intake. has some sort or weird air box right over the valve cover, is this like just a variant? Better or worse? Worth buying?
The box can be removed and a resonator only. Seal the hole with expanding rubber freeze plug and hose clamp. They have a tendency to scar up the valve cover when dirt gets caught under them to then vibrate against the cover like sand paper.
